TECHNICAL FIELD

Exemplary embodiments relate generally to electronic content distribution and, more specifically, to methods and computer program products for subcontent tagging and playback.

BACKGROUND

In today's busy and harried society, program viewers may not have sufficient time or inclination to view a broadcast program in its entirety. For example, a viewer desires to watch the weather portion of a local newscast, but has no interest in sports or national news. Similarly, a viewer may be interested in watching a contestant of special interest on a reality-based program involving a talent competition, but does not wish to spend the time viewing numerous other competitors. Moreover, a typical cable television or internet protocol television (IPTV) system may offer a multiplicity of real time broadcast channels such as CBS, NBC, ABC, PBS and FOX, as well as a number of channels offering movies or other programming on request. Viewers may wish to switch back and forth between two or more programs of interest being broadcast on two or more different channels. Although present-day digital video recorders are typically equipped with rewind and fast-forward functionality, it may be inconvenient and cumbersome to locate one or more desired portions of a program while excluding undesired portions.

DETAILED DESCRIPTION

In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of embodiments. However it will be understood by those of ordinary skill in the art that the embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the embodiments.

FIG. 1 is a simplified block diagram of an exemplary communication system used to perform subcontent tagging and playback. A content provider 102 provides programming that includes one or more live broadcast programs and, optionally, one or more prerecorded programs. The content provider 102 is illustratively implemented using a head end for receiving and processing a plurality of broadcast channels such as CBS, NBC, ABC, FOX, and ESPN to provide program streams for each of the plurality of broadcast channels. The content provider 102 is operatively coupled to a network 100. Illustratively, the content provider 102 may, but need not, include one or more access servers and one or more delivery servers.

A non-exhaustive list of examples for the network 100 includes wired or optical networks such as the Internet, intranets, Ethernet networks, token rings, Universal Serial Bus (USB), wired networks according to the IEEE 1394-1995, IEEE 1394a-2000, and IEEE 1394b standards (commonly known as “FireWire”), or any combination thereof. The network 100 may include any combination of additional communication devices (not shown) such as gateways, routers, switches, and the like. Additionally or alternatively, the network 100 may include wireless networks such as Direct Sequence--Code Division Multiple Access (DS-CDMA), Global System for Mobile Communications (GSM), North American Digital Cellular (NADC), Time Division Multiple Access (TDMA), Extended-TDMA (E-TDMA), W-CDMA, GPRS, GSM, Enhanced Data for GSM Evolution (EDGE), 3G and 4G communication, wireless local area networks such as 802.11, Bluetooth™, Zigbee™, ultra wideband (UWB), or various combinations thereof.

A digital video recorder (DVR) 106 is operatively coupled to the network 100. The DVR 106 includes a receiving mechanism for receiving one or more broadcast programs from the network 100. According to exemplary embodiments, the DVR 106 also includes a storage mechanism, operatively coupled to the receiving mechanism, that is capable of storing one or more broadcast programs received from the network 100 for subsequent playback on a display mechanism 113. The display mechanism 113 is also capable of displaying a first thumbnail 115 and a second thumbnail 116. In accordance with exemplary embodiments, the first thumbnail 115 represents a first video frame of a first clip 105 and the second thumbnail 116 represents a first video frame of a second clip 107. The first thumbnail 115 and the second thumbnail 116 may, but need not, be similar in appearance to scene change still images commonly present on prerecorded DVD movies. Optionally, the display mechanism 113 is capable of displaying a playlist of one or more thumbnails that have been selected by a user for future playback using a selection mechanism 114.

The selection mechanism 114 may accept user input for selecting a thumbnail such as the first thumbnail 115 or the second thumbnail 116. Illustratively, the selection mechanism 114 may be implemented using a keypad, keyboard, touch-sensitive display screen or remote control. The selection mechanism 114 could, but need not, be integrated into the DVR 106 or into the display mechanism 113 or both. Optionally, the selection mechanism 114 permits a user to switch back and forth between viewing a clip, such as the first clip 105, and viewing an entire broadcast program from which the clip was obtained.

As illustrated in FIG. 1, the content provider 102 transmits a content 108 to the network 100. According to exemplary embodiments, the content 108 includes a broadcast program commencing at 0:00 and ending at 1:00. A first begin tag 121 and a first end tag 122 define a beginning time and an ending time for the first clip 105. Similarly, a second begin tag 123 and a second end tag 124 define a beginning time and an ending time for the second clip 107. Illustratively, the first begin tag 121, the first end tag 122, the second begin tag 123, and the second end tag 124 are each implemented using extensible markup language (XML) tags with time stamps. For example, a first time stamp defines a beginning time for the first clip 105, and a second time stamp defines an ending time for the first clip 105. Illustratively, the first clip 105 and the second clip 107 may be emailed to one or more destination addresses over the network 100 by an email-enabled DVR, such as the DVR 106, or by a computing device used in conjunction with the DVR 106.

According to exemplary embodiments, XML tags are editable and also permit entry of commentary associated with the first clip 105 or the second clip 107 or both. XML tags may, but need not, be used to provide a pop-up message or advertisement in the first clip 105 or the second clip 106, or both. Likewise, XML tags may be used to blank out a certain number of lines of program material at the top or bottom of a screen displayed by the display mechanism 113, so as to permit textual or graphical information to be inserted into the blanked out lines. XML tags can be used to provide a message or advertisement that persists on the screen of the display mechanism 113 for a certain amount of time, such as five seconds.

According to exemplary embodiments, the content 108 includes a wrapper 109 after the end of the broadcast program. The wrapper 109 includes wrapper information comprising at least one of a sponsor advertisement, a trailer broadcast, a header broadcast, or a summary of one or more video clip segments such as the first clip 105 or the second clip 107.

FIG. 2 is a flowchart of an exemplary procedure for performing subcontent tagging and playback. The procedure commences at block 201 where a content provider (such as the content provider 102 of FIG. 1) inserts at least one begin tag 121 (FIG. 1) and at least one end tag 122 into a broadcast program. The at least one begin tag 121 and at least one end tag 122 defines a video clip segment for the broadcast program, such as first clip 105. Next, at block 203 (FIG. 2), the content provider 102 transmits the broadcast program including the at least one begin tag 121 and the at least one end tag 122 over a network (such as the network 100, FIG. 1) to a digital video recorder (DVR 106, FIG. 1).

The procedure advances to block 205 (FIG. 2) where the DVR 106 (FIG. 1) receives the broadcast program including the at least one begin tag 121 and the at least one end tag 122. The DVR 106 then stores the video clip segment for the broadcast program (FIG. 2, block 207). The DVR 106 associates the video clip segment with a thumbnail comprising a first video frame from the video clip segment (block 209), For example, the DVR 106 may associate a video clip segment comprising the first clip 105 (FIG. 1) with the first thumbnail 115, wherein the first thumbnail 115 comprises a first video frame of the first clip 105. Similarly, the DVR may associate a video clip segment comprising the second clip 107 with the second thumbnail 116, wherein the second thumbnail 116 comprises a first video frame of the second clip 107.

At block 211 (FIG. 2), upon the broadcast program ending, the content provider 102 (FIG. 1) transmits a wrapper, such as the wrapper 109, over the network 100 to the DVR 106. According to exemplary embodiments, the wrapper 109 includes wrapper information comprising at least one of a sponsor advertisement, a trailer broadcast, a header broadcast, or a summary of one or more video clip segments. Next, at block 213 (FIG. 2), the DVR 106 (FIG. 1) receives the wrapper 109. The DVR 106 initiates a display of the thumbnail for the video clip segment (block 215, FIG. 2). For example, the DVR 106 (FIG. 1) may initiate a display of the first thumbnail 115 for the first clip 105 and the second thumbnail 116 for the second clip 107 on the display mechanism 113.

The procedure of FIG. 2 advances to block 217 where, in response to the DVR 106 (FIG. 1) receiving a user's selection of a thumbnail such as the first thumbnail 115 or the second thumbnail 116 over the selection mechanism 114, the DVR 106 initiates playback of a video clip segment corresponding to the selected thumbnail and playback of at least a portion of the wrapper 109. For example, if the user selects the first thumbnail 115, the DVR 106 initiates playback of first clip 105 and also plays back at least one of a sponsor advertisement, a trailer broadcast, a header broadcast, or a summary of one or more video clip segments included in the wrapper 109. A header broadcast may include program material inserted prior to a video clip segment, such as first clip 105, whereas a trailer broadcast may include program material inserted after a video clip segment.
